How Installing Energy-Efficient Windows in Windham Saves You Money

There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:

  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Upgrading to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Windham, that’s about 147 pounds per year on average.

Estimated Cost of Window Replacement in Windham

Windows come in varying shapes, purposes and styles, so costs and services will differ considerably depending on several factors. Below, we detail the average cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

According to our research, the average cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. But costs will vary significantly depending on the number of windows you need, your location, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase overall project costs.

It’s important to keep in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Windham homeowners $457+ a year when replacing single-pane windows.

Asking for free quotes from several companies is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first step when planning a window replacement is to clarify whether you want a full-frame or pocket installation.

Full-frame installations involve replacing the total window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has significant deterioration. Because these installations are more involved, they will raise the overall cost. Pocket installations are on the simpler end and won’t carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re still trying to decide which kind of installation you need, you can ask your provider and get their advice. The choice mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Windham

EcoWatch is different from other reviewers, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Windham and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have good feedback about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a hefty investment, so you’ll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Windham, CT Window Replacement FAQs

How much should window installation cost?

The average cost to replace one window ranges between $450 and $650. There are several factors that influence the cost, including how energy-efficient the windows are, the number of windows, local labor costs, the materials used in designing the windows, your property’s location and styles and sizes of windows.

What are the most common kinds of replacement windows?

The most common types of windows for homes are casement windows, slider windows, double-hung and single-hung windows, transom windows, bay windows, picture windows and awning windows.

When do I have to use a window installation company?

Unless you have experience with home improvement projects and have the tools needed to replace your own windows, we recommend hiring a professional. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and much safer option.

How long does window installation generally take?

Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
